Abstract

Semiconductor devices are an integral part of our world and are used in analog and digital applications on Earth and in space because they are cheap, small, fast, lightweight, and provide high functionality. However, their use in radiation environments - as is the case with space applications - can have serious consequences that may affect the performance of devices and systems in terms of correct functioning, service life and even destruction of the electronic components and/or systems used and therefore represent a risk for any space mission. Many findings on these phenomena have been compiled and documented in the literature (e.g. [1] - [5]). This presentation will give an overview on the main types of radiation effects that may occur in electronics when exposed to various radiation sources. 

When designing a specific application, knowledge of the radiation sensitivity of the parts used is crucial to ensure a successful mission or at least to reduce the risk of failure. Therefore, testing may be required to gain adequate knowledge of their sensitivity to a given radiation environment [6]. This presentation will give an overview on test strategies and will also give an overview on the most relevant test standards.
